1 + FBINTF Change Log  version          (1.4-0 Build 12952) Tue, 07 Dec 2021 11:53:46 +0000
2 +
3 + 1. Client side journaling support added. Interface changes
4 +   IAttachment
5 +    function JournalingActive: boolean;
6 +    function GetJournalOptions: TJournalOptions;
7 +    function StartJournaling(aJournalLogFile: AnsiString): integer; overload;
8 +    function StartJournaling(aJournalLogFile: AnsiString; Options: TJournalOptions): integer; overload;
9 +    procedure StopJournaling(RetainJournal: boolean);
10 +
11 + 2. Transactions may now be given a local transaction name:
12 +   IFirebirdAPI
13 +     function StartTransaction(Attachments: array of IAttachment;
14 +             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
15 +             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit;
16 +             aName: AnsiString=''): ITransaction; overload;
17 +     function StartTransaction(Attachments: array of IAttachment;
18 +             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
19 +             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit;
20 +             aName: AnsiString=''): ITransaction; overload;
21 +
22 +   IAttachment
23 +    function StartTransaction(TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
24 +    function StartTransaction(TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
25 +    function StartTransaction(TPB: array of byte;
26 +                              DefaultCompletion: TTransactionCompletion=taCommit;
27 +                              aName: AnsiString=''): ITransaction; overload;
28 +    function StartTransaction(TPB: ITPB;
29 +                              DefaultCompletion: TTransactionCompletion=taCommit;
30 +                              aName: AnsiString=''): ITransaction; overload;
31 +
32 +  ITransaction
33 +    function GetTransactionName: AnsiString;
34 +    procedure SetTransactionName(aValue: AnsiString);
35 +
36 + 3. Additional Transaction information
37 +     ITPB.function AsText: AnsiString; {Returns TPB as a text string}
38 +
39 +   ITransaction
40 +     function GetDefaultCompletion: TTransactionCompletion;
41 +     function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction}
42 +
43 + 4. New IAttachment helper functions
44 +     function HasTable(aTableName: AnsiString): boolean;
45 +     function GetAttachmentID: integer;
46 +
47 + FBINTF Change Log  version          (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
48 +
49 + 1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
50 +
51 + 2. Remove constraint in IAttachment.HasScollableCursors that returned false when
52 +   using remote protocol. Scrollable cursors with remote database expected to
53 +   be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
54 +   a not supported error.
55 +
56 + 3. IStatement: new function;
57 +    TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
58 +    TStatementFlags = set of TStatementFlag;
59 +    function GetFlags: TStatementFlags;
60 +
61 + 4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
62 +   compatibility.
63 +   In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
64 +   type changes from ExecProcedure to Select. So that ExecuteQuery can continue
65 +   to be used with Update...Retruning statements that return a singleton row,
66 +   instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
67 +   it will open the cursor and return the first row only.
68 +
69 + 5. ITransaction: new functions:
70 +    function GetIsReadOnly: boolean;
71 +    function GetTransactionID: integer;
72 +    function GetTrInformation(Requests: array of byte): ITrInformation; overload;
73 +    function GetTrInformation(Request: byte): ITrInformation; overload;
74 +
75 +   The latter two return the Transaction Information block. The first two extract
76 +   information the Transaction Information block
77 +
78 + 6. New function TSQLTokeniser.ReadCharacters
79 +   Used internally.
80 +
81 + 7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
82 +   parameter placeholders instead of named parameters.
83 +
84 + 8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
85 +   transaction handle is now ignored if Rollback/Commit is called with Force=true
86 +
87 + FBINTF Change Log  version          (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
88 +
89 + 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
90 +
91 + 2. IStatement: new methods:
92 +    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
93 +    function GetStaleReferenceChecks: boolean;
94 +
95 +   In previous versions, stale reference checks were always enabled. This allows the
96 +   user to disable them on a per statement basis. Note this can risk out-of-date
97 +   statement BLR. See User Guide.
98 +
99 + 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
100 +   stored procedure and hence avoids replacing named parameters within a containing
101 +   BEGIN..END block.
102 +
103 + 4. ISQLParam: using a string value to set an integer field with a scale factor of
104 +   zero is now treated as a special case to avoid the risk of floating point
105 +   rounding errors affecting pure integers.
106 +
107 + 5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
108 +
109 + 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
110 +   SQL Parameter metadata (methods moved from ISQLParam).
111 +
112 + 7. ISQLParam: new method
113 +     function getColMetadata: IParamMetaData;
114 +   This instance of IParamMetaData returns the original column metadata which is unmutable.
115 +   Note: ISQLParam metadata can change after a parameter value has been set e.g when
116 +   setting a VARCHAR column to an integer value.
117 +
118 + 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
119 +    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
120 +   also IAttachment:
121 +    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
122 +    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
123 +    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
124 +                       aSQLDialect: integer; GenerateParamNames: boolean=false;
125 +                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
126 +    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
127 +                       GenerateParamNames: boolean=false;
128 +                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
129 +
130 + 9. Support for scrollable cursors added. New/updated methods:
131 +   IAttachment:
132 +    function HasScollableCursors: boolean;
133 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
134 +                             Scrollable: boolean=false): IResultSet; overload;
135 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
136 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
137 +                             params: array of const): IResultSet; overload;
138 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
139 +                             params: array of const): IResultSet; overload;
140 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
141 +                             params: array of const): IResultSet; overload;
142 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
143 +                             Scrollable: boolean=false): IResultSet; overload;
144 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
145 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
146 +                             params: array of const): IResultSet; overload;
147 +    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
148 +    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
149 +                             params: array of const): IResultSet; overload;
150 +   IStatement:
151 +     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
152 +   IResultSet:
153 +    function FetchPrior: boolean; {fetch previous record}
154 +    function FetchFirst:boolean; {fetch first record}
155 +    function FetchLast: boolean; {fetch last record}
156 +    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
157 +    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
158 +    function IsBof: boolean;
159 +
160 + 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
161 +
162 + 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
163 +    may be noticeable when a line separator occurs inside quoted text. The quoted text
164 +    output by the tokeniser will now use the platform specific lineEnding regardless
165 +    of whether the input uses the CRLF or LF as a line separator.
166 +
167 + 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
168 +
169 +
170 + FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
171 +
172 + 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
173 +
174 + 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
175 +   will now be encoded inline (i.e. as part of the parameter buffer) if they are
176 +   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
177 +   separate server interaction. This is intended as a performance optimisation.
178 +
179 +   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
180 +   IAttachment interface functions:
181 +
182 +    function GetInlineBlobLimit: integer;
183 +    procedure SetInlineBlobLimit(limit: integer);
184 +
185 + 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
186 +   user as the functionality is embedded in the implementation of the IStatement
187 +   interface. Three new functions are defined:
188 +
189 +    procedure AddToBatch;
190 +    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
191 +    procedure CancelBatch;
192 +    function GetBatchCompletion: IBatchCompletion;
193 +    function GetBatchRowLimit: integer;
194 +    procedure SetBatchRowLimit(aLimit: integer);
195 +
196 +   Also
197 +
198 +    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
199 +    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
200 +
201 +   For more information see the User Guide.
202 +
203 + 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
204 +   provided with the EIBInterBaseError now include all three parts.
205 +
206 + 5. Firebird.pas and include files updated to Firebird 4.0.0
207 +
208 + 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
209 +   Returns SQL Statement type as a text string;
210 +
211 + 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
212 +   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
213 +
214 + FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
215 +
216 + 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
217 +   typo in FB30Statement.pas that caused an unknown parameter error.
218 +
219 + FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
220 +
221 + 1. Imported (Firebird) constants updated for Firebird 4.
222 +
223 + 2. Firebird.pas from Firebird 4 integrated into source code tree.
224 +
225 + 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
226 +
227 + 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
228 +
229 + 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
230 +   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
231 +   interface provides a single method "function GetIMasterIntf: IMaster". This provides
232 +   type safe access to the Firebird IMaster interface and avoids the need to turn
233 +   off object checks when coercing "function GetIMaster: TObject" to IMaster.
234 +
235 + 6. New IFirebirdAPI Calls:
236 +    function HasLocalTZDB: boolean;
237 +    function HasTimeZoneSupport: boolean;
238 +    function HasExtendedTZSupport: boolean;
239 +    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
240 +    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
241 +
242 + 7. New IAttachment Calls:
243 +    function HasDecFloatSupport: boolean;
244 +    function GetTimeZoneServices: ITimeZoneServices;
245 +    function HasTimeZoneSupport: boolean;
246 +
247 + 8. New Interface ITimeZoneServices.
248 +
249 + 9. New ISQLData API Calls:
250 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
251 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
252 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
253 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
254 +    function GetAsUTCDateTime: TDateTime;
255 +    function GetAsBCD: tBCD;
256 +
257 + 10. New ISQLParam API Calls
258 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
259 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
260 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
261 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
262 +    function GetAsUTCDateTime: TDateTime;
263 +    function GetAsBCD: tBCD;
264 +    function GetStatement: IStatement;
265 +    function GetTransaction: ITransaction;
266 +    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
267 +    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
268 +    procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
269 +    procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
270 +    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
271 +    procedure SetAsBcd(aValue: tBCD);
272 +
273 + 11. New IArray API Calls
274 +    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
275 +    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
276 +    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
277 +    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
278 +    function GetAsUTCDateTime(index: array of integer): TDateTime;
279 +    procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
280 +    procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;
281 +    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
282 +    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
283 +
284 + 12. Utility functions in IBUtils
285 +    function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
286 +              var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
287 +    procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
288 +    function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
289 +    function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
290 +    function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
291 +    function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
292 +
293 + 13. IDPB, ITPB and ISPB: new interface method
294 +      function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
295 +    This is used to add a parameter block item by the string equivalent of its
296 +    symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
297 +
298 + 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
299 +      function getParamTypeName: AnsiString;
300 +
301 + 15. fb_shutdown now called before unloading Firebird library. This can avoid a
302 +     SIGEVENT error when a programme using the embeded server is unloaded.
303 +
304 + FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
305 +
306 + 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
307 +   with a Firebrid 3 client library.
308 +
309 + 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
310 +    If a client library path is not explicitly provided and the FIREBIRD environment
311 +    variable is set then the directory given by this variable and any 'lib' subdirectory
312 +    are searched for the Firebird client library. Only if none is found, is the default
313 +    client library used.
314 +
315 + 3.  IUtil.FormatStatus now used to format error messages when using new API
316 +
317 + 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
318 +
319 + 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
320 +    returned using GetAsString and the string codepage is UTF8, the string is truncated so
321 +    that the byte length corresponds to the number of characters specified for the column.
322 +    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
323 +    correct behaviour but may affect some implementations that relied upon automatic
324 +    trimming of trailing white space.
325 +
326 + 6.  New IFirebirdAPI Calls:
327 +      function GetClientMajor: integer;
328 +      function GetClientMinor: integer;
329 +
330 + 7.  IColumnMetaData and IArrayMetaData: new method
331 +      function GetCharSetWidth: integer;
332 +
333 + FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
334 +
335 + 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
336 +   case sensitive
337 +
338 + 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
339 +
340 + 3. New API Calls:
341 +        IColumnMetaData.GetStatement
342 +        IColumnMetaData.GetTransaction
343 +        ISQLData.GetStrDataLength
344 +        IResults.GetStatement
345 +        IAttachment.OpenBlob (using Blob metadata)
346 +        IAttachment.OpenArray (using array metadata)
347 +
348 + 4. FBMessages: removal of unused messages
349 +
350 + 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
351 +
352 + 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
353 +
354 + FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
355 +
356 + 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
357 +   where the second character of the parameter name is a numeric.
358 +
359 + 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
360 +   This returns the isc_version connection information as one or more lines.
361 +   This is the same information as returned by isql with the -z option.
362 +
363 + 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
364 +   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
365 +   compiler option then the Firebird 3 API is no longer compiled in.
366 +
367 + 4. IColumnMetaData: new method.
368 +
369 +   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
370 +                        dfDateTime,   {SQL DATETIME}
371 +                        dfTime);
372 +
373 +   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
374 +
375 +   This returns the max. number of characters returned by the "AsString" method
376 +   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
377 +
378 + 5. Additional argument for IAttachment.PrepareWithNamedParameters -
379 +     CaseSensitiveParams: boolean = false

388 +   using .AsString.
